INTERLOCKING SHEET FILING Filed Nov. 23, 1928 Patented Nov. 22, 1932 UNITED STATES ARTHUR MAUTERER, OF DOR'IIVLUND; GERMANY INTERLOCKING SHEET PILING Application filed November 23, 1928, Serial No.

It has been suggested in connection with interlocking sheet piling having a head on one edge of one pile and a C-shaped jaw along the edge of the adjacent pile to so arrange the head that any bending moments which occur are rendered substantially non injurious. In this manner a favourable resistance against strains in the longitudinal direction, as particularly occur during ramming, is obtained.

The present invention relates to a further improvement of this arrangement in that for example in the case of plates of Z-shape the connection is disposed towards the inside.

By this arrangement there is not only obtained an entirely smooth surface on the outside, but the resistance becomes at the same time more favourable against turning.

In the drawing will be found sectional views of three different embodiments of which the present invention is susceptible.

Referring to the drawing and particularly to Fig. 1 the pile f has an enlarged end 9 within which the socket h is formed. The

5 end of the pile f is inclined as at in in a plane intersecting the plane of the outer surface of the pile. The pile 2' has an extension Z disposed in the same plane as the end 9, and carries the head on to engage in socket n in a plane intersecting the plane in which the body or surface of the piles f and i are located.

A similar construction is shown in Fig. 2 where the pile f has an enlarged end g with a socket it formed therein, and the pile 2' has the extension Z carrying the head on. In this embodiment of the invention, the socket la is of slightly different configuration than the sockets heretofore described having a curved surface and two converging straight surfaces, while the head m is cut away opposite its curved surface to provide pointed ends to contact the converging sides of the socket and the head is disposed in a plane substantially at right angles to the surface of the pile.

In Fig. 3, an arrangement similar to Figs. 1 and 2 is shown except that the extension Z has a portion n beyond the head m and contacts the end at opposite sides of the 321,325, and in Germany November 23, 1927.

socket h. The head is similar to that shown in Fig. 2 but is disposed in the socket at a different angle relative to .the outer surfaces of thepiles f and i".

In all of the embodiments above described the sections are brought together with the edge of one abutting theend of the otherand with the extensions disposed through the opening of thesocket which is in the direction of the edge of the pile on which it is carried, and with the head on the end of the extension located within the socket remote from the abutting ends and disposed in a plane intersectingthe plane in which the face of the piles is located. The construction and arrangement is such that the piles are positively locked together with very little relative movement'being possible and hence little likelihood of damaging strains von the joint such as occur during ramming.

I claim: 4

1. Interlocking means "for sections of sheet piling adapted to be assembled to present a flat surface at one face of thepiling comprising an'oifset extension on one section inclined to the plane of the face ofthe section, the other member having'the face of its end inclined in the sameplane as said. extension for abutting engagement therewith, an open socket formed .in said end and opening on said inclined face, and ahead on saidextension engageable in said socket when said sections are assembled with said inclined fface abutting said extension.

2. Interlocking means for sections of sheet piling adapted to be assembled topresentia flat surface at one face of the piling comprising an offset extension on -onesection inclined to the plane ofthe face of the section, the other member having an enlarged end with its face inclined in the same plane as said extension for abutting engagement therewith, an'open socket formed in said ,endand opening on said inclined face, and ahead on said extension engageable in said socket when said sections are assembled with said inclined face abutting said extension.

3. Interlocking means for sections of sheet piling adapted to be assembled to present a flat surface at one face of the piling comprising an offset extension on one section inclined to the plane of the face of the section, the other member having the face of its end inclined in the same plane as said extension for abutting engagement therewith, an open socket formed in said end and opening on said inclined face, and a head on said extension engageable in said socket when said sections are assembled with said inclined face abutting said extension, said head forming a beak which projects transversely to the plane of the flat surface formed by adjoining faces of the piling.

4. Interlocking means for sections of sheet piling adapted to be assembled to present a flat surface at one face of the piling comprising an'ofiset extension on one section inclined to the plane of the face of the section, the other member having an enlarged end with its face inclined in the same plane as said extension for abutting engagement therewith, an open socket formed in said end and opening on said inclined face, and a head on said extension engageable in said socket When said sections are assembled with said inclined face abutting said extension, said head forming a beak which projects transversely to the plane of said flat surface formed by the adjoining faces of the piling and the head having a curved portion extending only partially along the inner wall of the socket.

5. A joint for iron pilings, comprising a pair of members, one having an arm extending obliquely and laterally therefrom and terminating in a head substantially at right angles thereto, the other member having one end arranged to abut against the' opposing side of said oblique arm and provided with an oblique recess to receive said head, the

last-named member also having an angular claw which bears against the outer side of said head and also against the outer side of said arm.

6. A joint for iron pilings, comprising a pair of members, one having an arm extending obliquely and laterally therefrom and terminating in a head substantially at right angles thereto, the other member havingone end arranged to abut against the opposing side of said oblique arm and provided with an oblique recess to receive said head, the last-named member also having an angular claw which bears against the outer side of said head and also against the outer side of said arm, in which said head has a recess in its outer side and the end of said angular claw is fitted in said recess.

In testimony whereof I have affixed my signature.
